(I work in a pet store. I’m the only manager on the floor, and one night a customer approaches my cashier with several receipts but no items.)
Customer: *points at a $50 product on her receipts* “Can you tell me what this is?”
(Items are usually listed on the receipt with a ten-digit UPC, a price, and a brief description. Sometimes the description clearly says what the item is, like, “tp collar blue,” but more commonly it’s a jumble of abbreviations and random letters. I look at the receipt and see that this case is the latter.)
Me: “Well, what did you purchase? If we can get a description of the item, we can go find its section and narrow it down to the matching UPC.”
Customer: “I don’t remember what I purchased! Can’t you just tell me what I bought?”
Me: “Unfortunately, ma’am, if we look up the UPC on the register, it will just give us the same description that’s on your receipt. Do you have any recollection at all about what you bought? Do you still have the item?”
Customer: “No! My mother is going to return it in another state! I just need to know what it is!”
Me: “So… your mother has your items? She will probably have better luck at the store where she returns it, since she has the actual purchase. Even without a receipt, they will at least have the item and barcode. Maybe you could ask her what she’s returning?”
Customer: *shoves the receipt at me again* “Are you telling me that you don’t know what I purchased? I have the receipt! Can’t you just type in the numbers somewhere and get a picture of the item or something?”
Me: “I’m sorry; ma’am, but our registers don’t have that feature.”
(The customer stormed out, completely enraged that I didn’t know what she’d purchased when even SHE didn’t know! Did she expect me to have the hundreds of thousands of items in the store memorized by their ten-digit UPC numbers?)
